15 Claims. (Cl. 229-34) This invention relates to improvements in cartons, and particularly to folding boxes, that is, .oxes that may be set; up and locked in the set up position.

It is the principal object of this invention to rovide a box that has its outer walls arranged so form the frustrum of a pyramid, and which box or carton is shipped to the user in such a position that it can readily be erected.

Another object of this invention is the prowision in a box or carton of the class above specitied, wherein the walls are more securely held in Josition after it has been set up.

It is the further object of this invention to provide a carton or box as above set forth, in which the walls may be formed to have a top thereto or a relatively sharp edge and in which all corners of the carton are finished, that is, show no raw edge of the material.

It is also an object of this invention to generally improve upon the construction of folding cartons which, when they are erected, have their outer walls arranged with respect to one another to form a frustrum of a pyramid, and which have inner walls normal or vertical to the base of the carton.

Other objects and advantages of the present invention should be readily apparent by reference to the following specification considered in conjunction with the accompanying drawings forming a part thereof, and it is to be understood that any modifications may be made in the exact structural details there shown and described, within the scope of the appended claims, without departing from or exceeding the spirit of the invention.

Fig. 16 is a transverse sectional view taken on line lG-IS on Fig. 15.

Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.

Cartons and boxes having their outer walls incline toward one another and incline with respect to the base thereof to form, in eiiect, the frustrum of a pyramid, are old, but the blanks heretofore employed in the formation and erection of said cartons has been difficult to handle, resulting in a limited use thereof. Furthermore, prior cartons or boxes of this type were difficult to maintain in their set up position due to the fact that the blank had the tendency to resume its normal flattened position, and no particularly restraining means were provided to discourage this tendency. By the present invention, cartons of the inclined outer wall type can be very readily and quickly set up, and are retained in said set up position.

Specifically, and referring to the drawings, Fig. 1 illustrates a blank cut and scored to provide a rectangle 20, which constitutes the bottom of the carton.

The said bottom 20 is defined by fold or score lines 2|, 22, 23, and 24, in which the score lines 2! and 23 may be designated the sides, while the score lines 22 and 24 may be designated the ends of the blank, but it should be understood that this nomenclature may be reversed since these designations are usually determined by the greater dimension of the box.

Score or fold lines 2| and 23 respectively, hingedly connect with the bottom 20 extensions 3 25 and 26 which are identical in construction and form the side walls of the box, and since they are identical it is deemed sufilcient if but one of them be described in detail. Accordingly, extension 26 is provided longitudinally thereof with fold or score lines 21, 28 and 29 dividing the extension into panels 30, 3|, 32, and 33. The panel 30 which in the erected carton forms the outer wall member, is defined by the score or fold lines 23 and 21, while the panel 3|, which in the erected carton forms the inner wall member, is defined by the fold or score lines 21 and 28. The panel 32, defined by fold or score lines 28 and A 29 may be designated as the take up panel in the partial erection of the blank, as will later be made clear, while the panel 33 is defined by the score or fold line 29 and adjacent edge of the blank, and may be designated the glue panel. The ends of the outer side wall panel 30 are defined by inclined score lines 34 and 35, while the outer ends of the inner wall panel 3| are defined by oppositely inclining cut lines 36 and 31. The inclined score or fold lines 34 and 35 respectively, hingedly connect to the panel 3|! flaps 38 and 39, which close the ends of the hollow walls resulting from the erection of the carton, as will later be made clear. Take up panel 32 has its ends defined by score or fold lines 40 and 4| respectively, hingedly connecting to the panel hold-down tabs 42 and 43, while the ends of the glue panel 33 are defined by cut lines in alignment with the score or fold lines 40 and 4|. The inner wall member panel 3| is provided near its opposite ends with slits 44 and 45 for cooperation with locking tabs subsequently to be described.

The score or fold lines 22 and 24 respectively, hingedly connect with the bottom panel 20 extensions 45 and 41 which are identical in construction, and which, in the erected carton, form the ends walls thereof, and since these extensions are identical, it is deemed sufiicient if but one of them be described in detail.

Accordingly, extension 41 is provided transversely with score or fold lines 48 and 49, thereby providing panels 59, and 52. The panel 50 which, in the erected carton, forms the outer end wall member, is defined by the score or fold lines 24 and 48, while the panel 5| is defined by fold or score lines 48 and 49, and in the erected carton constitutm the inner end wall member. The pane152 in the erected carton constitutes a spacer for the lower ends of the end wall members and is defined by the fold or score line 49 and end of the blank. The ends of the end wall outer member panel 50 is defined by inclined score or fold lines 53 and 54, While the ends of the end wall inner wall member panel 5| are defined by cut lines 55 and 56. The ends of the spacer panel 52 are likewise defined by cut lines in alignment with the cut lines 55 and 55. The inclined score or fold lines 53 and 54 respectively, hingedly connect to the panel 50 foldable flaps 51 and 58 shown as substantially triangular in area and cooperate with the side wall holddown tabs as will later be made clear. The panel 5| has projecting respectively from its ends 55 and 56 locking tabs 59 and 59, which cooperate with the inner side wall members slits.

The operation of the blank of Fig. 1 is as follows:

The blank is cut and scored substantially as illustrated in Fig. 1, whereupon the glue panel 33 is folded on the fold or score line 29 onto the take up panel 32 and adhesive 6| applied to the said glue panel 33. The inner side wall member panel 26 and take up panel 32 with the glue panel thereon, are then folded on the score or fold line 21 to bring the adhesive on the glue panel 23 into contact with the bottom panel 20 adjacent the score or fold line 23. Pressure is then applied to cause the adhesion of the parts to one another. This is illustrated clearly in the upper end of Fig. 1, it being understood that both extensions 25 and 26 are similarly treated and arranged. It is in this condition that the cartons are shipped to the user.

In order to set up the carton, the user merely elevates the side walls from their fiat to their upstanding position, thereby arranging the side walls as illustrated in Figs. 2 and 4. It should be notedat this point, that the outer wall member 30 has a. greater transverse dimension than the inner wall member 3| has. Wherefore, in order to arrange the side walls with their inner end previously fastened to the bottom 20. this difference in dimension must be taken up. Therefore the take up panel 32. As seen in Fig. l, at the upper end thereof the glue panel 33 and outer wall member 30 have a combined transverse dimension substantially equal to the combined transverse dimension of the take up panel 32 and inner wall member panel 3|.

After the side walls have been raised from their fiat position they are in the positions illustrated in Fig. 2, whereupon the end walls are folded into position as illustrated by the left-hand end wall of Fig. 2. This erection of the end wall is efiected by holding inwardly the closure flaps 38 and 39 so that they rest against the edges of the side wall inner members 36 and 31, thereby closing the ends thereof, The end wall hold down flaps 51 and 5B are then folded on their respective score or fold lines 53 and 54, bringing their outer edges onto the side wall hold down tabs 42 and 43 at the line of the crease or fold lines 40 and 4|. The spacer fiap 52 is at this time, or may have previously been, folded on its score or fold line 49 to be normal to the inner end wall panel 5|. The end extension is then raised as a whole about its respective fold or crease line 22 or 24 so that the outer end wall member panel 50 engages the inclined end of the side walls. All that remains now is to fold inwardly the inner end wall panel 5| to lie normal to the bottom panel 20, at which time the locking tabs 59 and 60 thereof enter the side inner wall member slits 44 and 45.

It will be noted that the hold down tabs 42 and 43 are folded beneath the hold down flaps 51 and 58, thereby locking the take up panel 32 against the carton bottom panel 20. It will be appreciated that any tendency of the side wall extensions to assume their original position, that is, fiat, will be resisted by the hold down flaps 51 and 58 since they cannot be dislodged without opening the end wall extension which, in turn, is locked by the tabs 59 and 50.

From the foregoing it will now be appreciated that there has been provided a carton or box of the frustrum of a pyramid type wherein the parts are held positively against inadvertent disalignment.

The blank of Fig. 9 and the carton formed therefrom in Fig. 10 is quite similar to that just described and illustrated in Figs. 1 to 4 inclusive. In this modification however, the take up panel 32 and fastening panel 33 are combined into one panel 52 provided with adhesive 63.

To make up for the difference in transverse dimension in the inner and outer side wall members so that they may be laid flat and parallel with the bottom panel 20 for shipment purposes, the inner wall member 3| is provided longitudinally with a crease or fold line 64, thereby providing a panel 65 between said crease or fold line 64 and the outer wall panel 30 or outer end wall crease or fold line 21.

With this construction the whole side extension is folded onto the bottom panel as illustrated at the upper end of Fi 9.

The erection of the blank from the folded position is the same as that above, except that the hold down flaps 51 and 5B of the blank of Fig. 1 become merely flaps 66 and 61 to avoid the raw edge of the outer end wall member and they are folded onto the inner surface of said end wall outer member 50. In final erection the fold or crease line 64 runs longitudinally of the inner side wall member and has a tendency to weaken this member, but can still be employed in certain kinds of industries, particularly where the goods packed therein hides the said crease or fold line and tends to strengthen the said inner side wall member. The cartons or boxes thus far described have the upper ends of their side and end walls respectively sharp, that is, of no breadth other than the thickness of the board due to the folding thereof substantially onto itself. In Figs. 5 to 8 inclusive, there is illustrated a blank and a carton in which the upper ends of the side and end walls have appreciable, in fact, considerable thickness. This is obtained by supplying the side wall extension with an extra panel 68 between the outer wall member fold line 21 and an addi tional fold or score line 69 in said extension. In this type of a box or carton it is desirable to have a reinforcing spacer immediately beneath the said end wall top member, wherefore the inner side wall member panel 3| instead of being defined by cut lines 36 and 31, is defined by inclined score or fold lines and H, which respectively hingedly connect thereto flaps I2 and 13. The flaps 12 and '13 are each provided with parallel score lines 1 3 and 15, hingedly connecting to the flaps, respectively, a spacer tab 16, and a hold down tab Ill.

The end extensions 46 and 41 are likewise slightly modified to provide at the ends of the inner end wall member 5| side spacer tabs 18 and 19. In addition, the said end wall extensions are provided with an additional panel 80, which corresponds to the side wall panel 68, and bounded by the fold or score line 48 and an additional score or fold line 8|. The hold down flaps 51' and 58' are given a slightly different contour from that in Fig. 1, whereby they are elongated so as to engage not only the hold down tabs 42 and 43 of the take up panel 32, but also to engage the hold down tabs ll of the flaps I2 and 13.

The blank is shipped to the user with the side extensions folded and secured as illustrated with respect to the upper extension of Fig. 5, and the erection of the carton is made as above described, the only difference being that the spacer tabs 18 and 19 are folded normal to the inner end wall member at the same time that the spacer panel 52 thereof is similarly folded,

In the modification illustrated in Figs. 11 to 13 inclusive, one of the side walls does not have its outer wall member inclining toward the inner wall member, but instead has its outer wall member normal to the bottom panel 20, and therefore parallel with the inner wall member. In this case, the inner wall member 30' and outer wall member 3| are of substantially the same trans- 6 verse dimension with the panel 68 therebetween. Also there is eliminated from the blank the hold down panel 32 of Fig. l with the glue panel 33 adjacent to the said inner wall member 3|. Since the inner wall member has its inner edge permanently secured to the bottom panel, no hold down tabs are required. The resulting carton has a longitudinally cross section as substantially illustrated in Fig. 4, but has a transverse cross section as illustrated in Fig. 13, with one wall having parallel inner and outer wall members and a top wall, and the other side wall having a vertical inner wall and an inclined outer wall with no top wall between them.

The modified blank in Figs. 14 to 16 inclusive provides a carton wherein both of the side walls are provided with inner and outer wall members parallel to one another, with half the end walls having the outer wall members inclining toward the center. It is believed that a specific description of the blank of Fig. 14 is unnecessary since the side wall extensions thereof are identical with the lower side wall extension of Fig. 11.

The carton resulting from the blank of Fig. 14 again has a longitudinal cross section substantially the same as that of Fig. 4, with a transverse cross section as illustrated in Fig. 16. It is believed that further description of this modification is unnecessary.

From the foregoing it will now be appreciated that there has been provided a carton or box which adequately meets the objects initially set forth, and one in which inclined outer wall members are employed and definitely held or locked in operative positions.
